Embodiment Construction

[0063]The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments that the present application can be used to implement. The directional terms mentioned in this application, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are for reference only The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the application, but not to limit the application. In the figures, structurally similar elements are denoted by the same reference numerals.

[0064] The XAO module in the existing display device is susceptible to interference from other signals, which causes a certain degree of disturbance in the detection voltage of the XAO module, and the level shifter cannot accurately judge the detection voltage of the XAO module from this disturbance, and the final display panel Normal display cannot be performed. Based on...

Abstract

The invention provides a drive circuit and a display panel, the drive circuit comprises a first processing module, a second processing module and a calculation module. The first processing module is electrically connected with the calculation module, and the second processing module is electrically connected with the calculation module. The first processing module is used for processing the working voltage detected by an XAO module; the second processing module is used for processing the output voltage of a level shifter. By detecting the working voltage detected by the XAO module and the output voltage of the level converter, when the working voltage detected by the XAO module is smaller than a first threshold voltage and the output voltage of the level converter is larger than a second threshold voltage, the detection function of the XAO module is closed. According to the technical scheme, the technical problem that when the XAO module is interfered by other signals, the level shifter cannot accurately obtain the detection voltage of the XAO module is solved. The normal display of the display equipment is guaranteed.

Description

technical field [0001] The present application relates to the display field, in particular to a driving circuit and a display panel. Background technique [0002] In recent years, with the display trend of thinning, liquid crystal displays (Liquid Crystal Display, LCD) have been widely used in the application of various electronic products, such as mobile phones, notebook computers and color TV sets. [0003] When the display device is turned off, the charge in the pixel needs to be released to avoid problems such as afterimage and flicker due to the long-term existence of the charge. In the prior art, the XAO module is often used to output the XAO signal to the driving circuit to turn on all the row output signals to release and neutralize the residual charge in the pixel. [0004] However, the XAO module is susceptible to interference from other signals, which causes a certain degree of disturbance in the detection voltage of the XAO module, and the level shifter cannot a...
